The image of the perfect quilt is in your mind when you start a project.
However, reality will inevitably strike when you're creating it.
A seam might turn out crooked. You might sew the wrong pieces together.
Whatever the mistake is, ripping out the seam is the only real solution.
Seam rippers, or stitch rippers as they're also known, are the tool for this job.
You'll want a good one.
Otherwise, you'll strain your hand, tear fabric by mistake, or have the tool break in your hand.
